Thanks guys, yes the Kehoe dovetail keys are really easy to work out, it probably took me a half hour to get going with the jig, highly recommended. The celtic cross engraving was done on a shopbot cnc. The wood: Melina (Gmelina arborea) works beautifully when engraved, any finish (in this case wipe on poly) absorbed along the engraved path darkens it quite a lot.
